Mom fucks while husband is away

Came to be babysitting the mom of a teenager when her mom is on her way to drop out of grad school, so she had her buddy bring her over. Meanwhile, her mom was away and the guy was fucking all messengers away. The mom saw him in the car and thought we were fit to fuck her in the car while she was away to a place nearby. That turns out she knew exactly what the fuck Mom was up to and our meats got the lucky bastard!
